The p block elements are grouped as follows:
13 (IIIB, IIIA): Boron group
14 (IVB, IVA): Carbon group
15 (VB, VA): Nitrogen group (or pnictogens)
16 (VIB, VIA): Chalcogens
17 (VIIB, VIIA): Halogens
18 (Group 0): Noble gases (excluding helium)
The p-block elements are the most diverse block in the periodic table (metals, non metals, metalloids, and inert gases). This means that they do not have a lot of similarities as a whole.
Since the shift from left to right is from metal to non metal, the metal elements tend to have less metallic property compared to s and d block elements. Metals in the p block elements are in general have lower melting points ans are softer compared to the transition metals.
